Exponential catastrophic backtracking (ReDoS) in marked
CVE-2022-21681
7.5HIGH
What is CVE-2022-21681?
Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression inline.reflinkSearch may cause catastrophic backtracking against some strings and lead to a denial of service (DoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.
